Royals left-hander Jason Vargas underwent an appendectomy less than two weeks ago, but he could be activated from the disabled list as soon as Sunday against the Indians.

It would be a rapid turnaround, but Andy McCullough of the Kansas City Starreports that Vargas made it through a 20-pitch bullpen session today. The Royals will likely see how he feels over the next couple of days before making an official announcement, but it sounds like a minor league rehab start might not be necessary before his return.

Vargas, who underwent an appendectomy on July 9, owns a 3.31 ERA and 82/29 K/BB ratio in 125 innings across 19 starts this season. He joined the Royals on a four-year, $32 million contract over the winter.
